A bot that uses a standard series of responses to what you type.
Invented by nerds so they can chat to an 'imaginary friend'.
MGonz is finally written up as a book chapter: Humphrys, Mark (2008), "How my program passed the Turing Test", Chapter 15 of Parsing the Turing Test: Philosophical and Methodological Issues in the Quest for the Thinking Computer, Robert Epstein, Gary Roberts and Grace Beber (eds.), Springer, 2008.
But if a man responded (using his credit card as instructed), they started to sound distinctly bottish.
Straight men, the majority of site-users, were paying to hook up with women who did not, for the most part, exist. Would also meet up in person if we get to know each other and think there might be a good connection. It was being contacted in a short space of time by multiple women who supposedly lived in his area, who hadn’t looked at his profile, and who sent him identical messages.
Real women did use the site, but they were massively outnumbered by fake ones. All things that might have passed unnoticed if the bots hadn’t been operating on such an industrial scale. But the sex industry is a serious player in the world of AI bots—more sophisticated programs that can learn from their interactions with humans, and produce novel, unscripted messages.
It seems to be due to physical stimulation (i.e., sense of touch) that individuals use sex dolls, and it is predominately a male-oriented pastime, however I predict that Virtual Reality sex, with other human-controlled avatars, and with AI-controlled avatars is probably going to be far more popular in the mass market than AI-controlled sex dolls.
Mostly what is missing in VR sex is full body “sensation;” however the eventual introduction to the mass market of full body sensation suits is inevitable.
